Different bacteria move in different ways and self movement is known as.....

Self-movement in bacteria is referred to as motility. This term specifically describes the ability of an organism to move independently using metabolic energy. In the context of bacteria, motility is critical for various biological processes, including responding to environmental stimuli, finding nutrients, and escaping harmful conditions.

Bacteria can exhibit different types of motility, such as swimming through liquid environments using flagella or gliding along surfaces without the need for flagella. Understanding motility is essential in microbiology, as it plays a significant role in bacterial behavior and interaction with their surroundings.

Other terms, such as migration, evolution, and locomotion, refer to broader concepts or specific contexts of movement but do not capture the specific ability of bacteria to move independently, making "motility" the most accurate choice in this scenario.
